Usepackage is a tool for managing the Unix
environment for a multi-tool, multi-platform site.
It is designed to simplify login scripts and allow
administrators to control users' environments
centrally. This tool should be considered
primarily designed for sites where users have to
deal with a number of different tools, or versions
of tools, that are installed in different
locations and require environment variables to be
set. This is particularly a problem for
developers, or anyone who has to manage a large
toolset across multiple platforms (e.g. different
versions of the Sun JDK which require various
environment variables to be set correctly). One or
more central configuration files control a number
of different "packages" and their associated
environment and dependencies for different
platforms (this includes the standard PATH,
MANPATH, and LD_LIBRARY_PATH variables). A single
user command, use, can be invoked to source the
appropriate environment information into the
users' current shell.

PDC is a desktop calculator in the 'bc' style with features designed for programmers. It does not support floating point math, but does provide all the C operators (logical, bitwise, shifts, etc.) and implements ISO C operator precedence. Additionally, functions are available to assist with 'bit bashing' tasks such as byte swapping and bit scanning.

AVInfo is a utility for displaying AVI, MPEG (1 and 2), OGM, MKV, and IFO (DVD) information. It returns the length of a clip, FPS, resolution, codec, audio and video bit rate, number of key frames, sound parameters, the number and type of streams, and the language for audio/subtitles. It then generates a file list with statistics (HTML, plain text, or CSV).

Signal Applications To Audio Networks is a program
aimed at different signal processing tasks. The
primary type of signals are audio signals. The
user describes networks of different modules using
a special language, and the modules are
dynamically loaded libraries. The system can be
used to create music from scratch, or to process
already created audio files, and depending on the
complexity of the network versus the capacity of
the host machine, everything can be done in "real
time".

The GUIShell project is a collection of utilities facilitating the use of the GTK+ toolkit in shell scripts through the gtkshell utility. The ACE configuration environment provides sample scripts utilizing gtkshell for desktop utilities. rootcat provides the ability to display messages to the root window using Xft, allowing one to write status display scripts.

cuetools is a set of utilities for working with
cue files and TOC files. It includes parsing, programs for
conversion between the formats, flexible printing cue/TOC information, and track breakpoint
printing.

OpenDaemon provides a model of work along with its
supporting APIs that allow anybody to implement a
server of any kind, for any protocol. Its main
goal is to help provide an advanced data storage
solution that is flexible enough to allow its user
to choose from a broad set of parsers, data
extractors, processors, or any other supporting
API. The generic server platform system is meant
to make development of the data storage solution
more open and distributable.

Nonpareil is a microcode-level simulator for HP calculators introduced between 1972 and 1982, including the HP-35, HP-45, HP-55, HP-25, HP-34C, HP-38C, HP-41CV, HP-11C, HP-12C, HP-15C, HP-16C, and other models. The necessary microcode is included, as is a microcode assembler. The GTK+ toolkit is used for the user interface.
